bonainvest developed an entire district following a competition and has now completed the final phase. This final phase of the Hübeli estate in Lyss is called Arnhof and comprises two semi-detached houses, each with 4.5 rooms, two multi-occupancy buildings with 3.5 to 5.5 room apartments as well as terraced family houses with 5.5 rooms each and car ports. The project is located on a slightly elevated site where no further building is permitted; abundant sunshine and light are therefore guaranteed.

The project was completed in cooperation with the wahlirüefli Architekten und Raumplaner AG architects’ practice of Biel. The buildings are Minergie certified. The Arnhof estate features low energy consumption. In addition, the apartments comply with bonacasa construction standards.
